Adding controls to custom extended gridview

Posted By:      Posted Date: October 20, 2010    Points: 0   Category :ASP.Net
 

Hey,

I have custom gridview that  inherit from the regular gridview.

On of the features is that is has a built in page size dropdown in an extra header row.

Another feature is that this extra header row has a place holder where aditional controls can be added but here is where I have some problems.

When I add a control that is created outside the gridview to the gridviews builtin placeholder and tries to do anything that performs a postback the gridview dissepears, but appears again on a new post back.

Here is the code for the gridview:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Security.Permissions;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Backend.BLL;
using Backend.DAL;
using Backend.IP;

namespace SharedGui
{
    public delegate void UpdateEventHandler();

    [
    AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal),
    AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal),
    ToolboxData("<{0}:GridViewCustom runat=\"server\"> </{0}:GridViewCustom>"),
    DisplayName("GridViewCustom"),
    Description("Extended gridview control")
    ]

Custom Controls in C# .NET

  
Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.
